There will be a number of overnight road closures in place on the M4 this week that are set to cause diversions and disruptions.
These M4 closures come as a result of maintenance and road works as well as structural inspections that are set to be carried out during the week.
The closures are set to take place in various locations up and down the M4 including near Newport, Port Talbot and Swansea.
As we look ahead, these are the sections of the M4 that will experience road closures this week (January 29 to February 4).
